_D_e_s_c_r_i_p_t_i_o_n:

     Functions to compute cumulative row Statistics.

_U_s_a_g_e:

     ## Default S3 method:
     rowCumsums(x, na.rm = FALSE, ...)
     ## S3 method for class 'timeSeries':
     rowCumsums(x, na.rm = FALSE, ...)
     ## S3 method for class 'zoo':
     rowCumsums(x, na.rm = FALSE, ...)

_A_r_g_u_m_e_n_t_s:

   na.rm: a logical. Should missing values be removed? 

       x: a time series, may be an object of class '"matrix"', 
          '"timeSeries"', or '"zoo"'. 

     ...: arguments to be passed. 

_V_a_l_u_e:

     all functions return an S4 object of class 'timeSeries'.

_N_o_t_e:

     The methods for the '"zoo"' methods are still preliminary and 
     untested. 'na.rm' is not yet supported in all case, please test.

_A_u_t_h_o_r(_s):

     Diethelm Wuertz for the Rmetrics R-port.

_E_x_a_m_p_l_e_s:

     ## Simulated Monthly Return Data:
        x = matrix(rnorm(24), ncol = 2)
          
     ## colStats -
        rowCumsums(x)
